Gel capsule comprising a plant cell

Abstract

Disclosed is a capsule including: an internal phase including at least one plant cell; and an external gel phase, that totally encapsulates the internal phase at its periphery, the external phase including at least one surfactant and at least one polyelectrolyte in the gel state.

1 . A capsule comprising :
 an internal phase comprising at least one plant cell; and   an external gel phase, that totally encapsulates said internal phase at its periphery, said external phase comprising at least one surfactant and at least one polyelectrolyte in the gel state.   
     
     
         2 . A capsule according to  claim 1 , in which the internal phase comprises a culture medium. 
     
     
         3 . A capsule according to  claim 1 , in which the plant cell or cells are algae cells. 
     
     
         4 . A capsule according to  claim 1 , in which the plant cell or cells are in suspension in the internal phase. 
     
     
         5 . A capsule according to  claim 1 , in which the polyelectrolyte is a polyelectrolyte reactive to multivalent ions. 
     
     
         6 . A capsule according to  claim 1 , wherein the capsule size is less than 5 mm. 
     
     
         7 . A method for culturing plant cells including a step of putting in culture at least one capsule according to  claim 1 . 
     
     
         8 . A method for producing a compound of interest, that includes:
 a step of putting in culture at least one capsule according to claim, said capsule comprising at least one plant cell that is capable of producing said compound of interest.   possibly, a step of elicitation of the plant cells included in said capsule; and   a step of recovering the compound of interest.   
     
     
         9 . Plant cells produced using the capsule according to one  claim 1 . 
     
     
         10 . A composition comprising at least one capsule according to  claim 1 . 
     
     
         11 . A capsule according to  claim 2 , in which the plant cell or cells are algae cells. 
     
     
         12 . The capsule of  claim 3 , wherein the algae cells are micro algae cells. 
     
     
         13 . A capsule according to  claim 2 , in which the plant cell or cells are in suspension in the internal phase. 
     
     
         14 . A capsule according to  claim 3 , in which the plant cell or cells are in suspension in the internal phase. 
     
     
         15 . A capsule according to  claim 1 , in which the polyelectrolyte is a polyelectrolyte reactive to multivalent ions. 
     
     
         16 . The capsule according to  claim 6 , wherein the capsule size is in a range of 50 μm to 3 mm. 
     
     
         17 . A capsule according to  claim 2 , wherein the capsule size is less than 5 mm. 
     
     
         18 . A capsule according to  claim 3 , wherein the capsule size is less than 5 mm. 
     
     
         19 . A capsule according to  claim 4 , wherein the capsule size is less than 5 mm. 
     
     
         20 . A method for culturing plant cells including a step of putting in culture at least one capsule according to  claim 2 .
